Thanks Chuck, we'll give that a try.
What process version is he using? Please go to calibration panel and make sure the current version is selected.
I had forgotten about that feature, Adriana. I'll have her check. However, on my computer, selecting an older version only changes the Basic panel. The Filmstrip area is unaffected.
This is almost certainly an older version of Camera Raw. Click on the preferences icon the Camera Raw dialog toolbar and look on the title bar of the Camera Raw preferences dialog.
Also, what is the host application (Photoshop, Bridge, AfterEffects, Photoshop Elements, etc) and version.
This is probably 32-bit Windows, which does not support the merge feature.
My student will check her Windows system and get back to me. Thanks for the reply, Thomas.
Indeed. Older laptop with 32 bit OS. I have not seen a 32 bit system in class in a long time. Thanks
